This example will also illustrate an interesting idea about systems. © 2007 Paul Dawkins 338 College Algebra Example 3 Solve the following system of equations using augmented matrices. 3x - 3 y - 6 z = -3 2 x - 2 y - 4 z = -2 -2 x + 3 y + z = 7 Solution Notice that this system is almost identical to the system in the previous example. The only difference is the number to the right of the equal sign in the second equation. In this system it is 2 and in the previous example it was 10. Changing that one number completely changes the type of solution that we’re going to get. Often this kind of simple change won’t affect the type of solut...
